Bethesda, Md.-based Honest Tea, a wholly owned subsidiary of The Coca-Cola Co., began rolling out its first integrated advertising campaign with the new tagline “Refreshingly Honest.” The ads highlight the true taste of Honest Tea beverages by emphasizing the company’s use of real, organic ingredients with a quirky playfulness that stays true to the brand, the company says.  This is Honest Tea’s first foray into TV commercials. The company also will extend the campaign to digital video, social media, out-of-home billboards and transit signage, as well as grassroots events around the country.
